ABSTRACT:
Methods, systems and computer program products are provided which utilize luminance in the reduction in resolution of high-resolution values of the color components to provide reduced-resolution values of the color components. These methods, systems and computer program products preferably reduce the resolution of the high-resolution-value of the color components for a picture element to provide reduced-resolution values based upon the difference in luminance between the high-resolution values of the color components and the reduced-resolution values of the color components. Preferably, the difference between the luminance of the high-resolution values of the color components and the reduced-resolution values of the color components is minimized.
